The extraction of precious metals from electronic waste water is a long-term challenge for sustainable economy, as thus, we are motivated to study and construct high-performance extracting materials for the selective stripping of precious metals e.g. gold from a mess of waste solutions.

Dynamic control of electromagnetic wave jamming is needed for protecting electronic devices working at gigahertz frequencies. We describe a method for modulating reflection and absorption of electromagnetic waves using micron-thick films of 2D carbides (MXenes).

The electric field and potential array could be regulated by the size and distribution of mesoporous in 2-dimensional nano-sieves. These findings enable deeper construction of nano-dielectrics and provide a different way to illustrate the intricate modification mechanism from macro to micro.

Through oxygen management, a Cd(O,S,Se,Te) region with gradient bandgap was incorporated at the front interface of Cd(Se,Te) solar cells to reduce interfacial recombination, demonstrating Cd(Se,Te) solar cells with a champion power conversion efficiency (PCE) of 20.03%.
